My girl is the same! She is slightly younger than lots of the babies at some of the groups but she just likes to watch them. I don’t think it really means anything some are just a bit more overwhelmed. We go to an art class now where there is only 4 babies including mine and she is a lot more vocal and interacts a lot more. We have been attending baby sensory since she was 7 weeks but she is still really quiet and just watches when we are there but it is a busy class.
Same, she really likes to watch other people and children! Once she's taken it all in she's happy to babble a bit.
My son is the same. We had a family wedding when he was 4 months old & Christmas dinner when he was 6 months old & both he cried so much which was unlike him
Yeah my little one is like this, sometimes he warms up and babbles but he gets overwhelmed in busy sensory over load places quite easily
